Mean concentration:  2.32 x 10-3 g/L at 20.0 ± 0.5 ºC
Range:                        1.96 x 10-3 to 2.70 x 10-3 g/L

Validation

The linearity of the detector response with respect to concentration was assessed over the nominal concentration range of 26.5 to 212 mg/L. This was satisfactory with a correlation coefficient of 1.000 being obtained.
